In order to facilitate research and sharing of modelling approach in the Agriculture domain for food security, possible interoperability settings for data and processes will be presented. This is more a best practice than something new as the standards already exist. Furthermore, analysing models and sub-models from their representations within a workflow encoding standard (graphical and XML: BPMN2.0) allow communities to share and combine their models into more complex modelling. These two aspect put data and processes at the same level within dedicated infrastructures. We will present the general GRASP-WRE principle (Geospatial Resources for Agriculture Species and Pests - Workflow Research Environment) and its genesis at the University of Nottingham.
OGC standards for data and processes OMG standards (the BPMN) to combine these
authoring models / composing models / sharing models (as WPS and as BPMN part of the metadata DescribeProcess)
Tool to present conceptual models but also to run them and do analytical things such as analysing error propagation global local visualising data (final outputs but also along the chains of processes
Papers on meta-rpopagation of uncertainty Cageo BPMN chaning of WPS i.e. quality infrmation is needed for both data and processes
This was syntactic interoperability mostly but this gives the step for semantic interoperability or for king the most of semantic intereoprebility i.e. when composing the workflow
Models may be made to operate at a given scale but they have an impact at different scales and upscaling /extrapolation or dowscaling may be required/desired at some point!
Workflow as a computational model but also as set and order of tasks to achieve
